Benefits of Vacuum Stuffing, Pumping & Portioning
Our twin-piston design allows for the gentlest handing to maintain product integrity while achieving high volume output.
- Superior particle definition and product integrity.
Our Opti stuffing and pumping system allows product to be diffused across the pump’s sheeting valve for the gentlest handling while maximizing vacuumization. This highly engineered design delivers premium whole muscle meats with the least amount of product damage.
- Optimal vacuumization.
Marlen’s patented twin-piston and sleeve design allow for maximum vacuumization throughout the system’s hopper and pumping chamber. By exposing the product to optimal removal of entrapped air and achieving up to 29” of mercury, better weight control is achieved, shelf life extended, and increased casing savings result through the delivery of denser products.
- Continuous flow.
Constant pressure and speed is maintained via Marlen’s hydraulic-powered and servo-driven pumps which retain the same pressure while stopped as when in motion. The result: a precise metered flow for better weight control at the speeds required for high volume production environments.
